Hoss 995 Posted July 9, 2015 Having trouble with the primer mechanism. Can anybody take some pics or vidio of theirs in action and send to me. I need to look at the underside of the primer tray, where the spring, chain and lever are located. I think mine may have gotten bent or something while not in use, and I cant sem to get it back working correctly. Especially the lever part. Being dyslesic makes trying to figure out these sorts of things especially difficult! send to: jrooney@brownwatermarine.com thanks! Share this post Link to post Share on other sites
John Boy 748 Posted July 9, 2015 Turn a tray of primers upside down next to the press. Then hand feed them into the primer seating die. Almost as fast as pulling the chain and then waiting for the primer to hopefully drop into the hole and fiddling moving the primers into the que. My primer feeder now has rested long term in a parts box! Share this post Link to post Share on other sites
Buckshot Frank 0 Posted July 9, 2015 I bought an old Sizemaster off of ebay years ago. The primer feed didn't work well when I received it, but I messed with it and got it to work. It has been going strong ever since. Let me take a look, and see if I can remember what the issue was. I seem to recall having to bend the bracket to get the angle just right.

Hoss 995 Posted July 9, 2015 I'm thinking something got bent. it was working fine last time I used it, put it on shelf in garage, next time it would not work properly. Share this post Link to post Share on other sites
Abilene Slim SASS 81783 2,279 Posted July 9, 2015 Don't know if this will help Hoss, but go to the bottom of page 5. Good luck! https://www.mecshootingsports.com/Images/document/sizemaster.pdf Share this post Link to post Share on other sites
Sedalia Dave 10,068 Posted July 9, 2015 Make sure the arm that actuates the feed is not bent. This is the arm that sits on top of the final crimp die. My 600 jr uses the same primer feed and I had a similar issue. The arm was catching the adjusting nut and causing the press to bind. Arm should ride on the outer portion of the die and not touch the lock nut. Share this post Link to post Share on other sites
Buckshot Frank 0 Posted July 9, 2015 Might help if you describe the failure. Is the arm actuating, not picking up a primer, primer getting stuck in the tube, etc? Share this post Link to post Share on other sites
Roger Rapid 216 Posted July 9, 2015 Hoss… Just sent a video of underside of primer tray during last two crimping steps (and primer loading step) to your email… … RR Share this post Link to post Share on other sites
